Note that J5 comprises the signals needed for a SMARTDM™ serial digital audio interface and I

C™

signals. The reset and power down (RESET and PWRDN) signals are routed to J4. I

C™ is actually

routed from the USB-MODEVM to both connectors; however, the codec and EEPROM are only connected

to J5.
